[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] A pre-installed electronic scale, such as Figure 1-6 As shown, it includes: a base 1, an electronic component 2, a sensor 3, a weighing pan 4, a widening component 5, and a support component 6; the base 1 is a hollow cavity, and the upper surface of the base 1 has a display window 11 and a connection port 12; the electronic component 2 is disposed inside the base 1, and the position of the electronic component 2 corresponds to that of the display window 11; the sensor 3 is disposed inside the base 1 and connected to the electronic component 2; the weighing pan 4 passes through the connection port 12 and is connected to the sensor 3; the widening component 5 is movably connected to the weighing pan 4; the support component 6 is movably connected to the weighing pan 4.

[0027] Specifically, by pre-integrating multiple electronic components into an independent electronic assembly 2, the tedious manual installation process in the assembly line is reduced. The electronic assembly 2 is pre-assembled and debugged in a relatively independent module, which can effectively reduce the probability of human error, improve the assembly accuracy and consistency of the product, thereby improving product quality and production efficiency and reducing production costs. The weighing pan 4 can be flexibly adjusted according to the size or shape of the item to be weighed. When it is necessary to weigh larger items or bagged items, the effective area of ​​the weighing pan 4 can be easily increased by using the widening component 5 and the support component 6, which can prevent the item from falling due to the weighing pan 4 being too small. The actual weight can be accurately measured without multiple weighings, which improves the accuracy and convenience of weighing.

[0028] In embodiments of this utility model, such as Figure 1-6 As shown, the base 1 consists of a base plate 13 and a support frame 14, and the base plate 13 and the support frame 14 are detachably connected. The base plate 13 is provided with mounting holes, and the support frame 14 is provided with mounting posts. The mounting posts are provided with internal threads. After the bolt passes through the mounting holes through the bottom of the base plate 13, it engages with the internal threads of the mounting posts to stably connect the support frame 14 and the base plate 13.

[0029] Specifically, the base 1 adopts a design where the base plate 13 and the support frame 14 are detachably connected. This facilitates quick disassembly of the base 1 when the electronic scale malfunctions, allowing for inspection and repair of internal components such as the electronic components 2 and sensors 3. Furthermore, the modular design of the electronic components 2 makes it easier to replace individual components, reducing repair time and costs and extending the lifespan of the electronic scale.

[0030] In embodiments of this utility model, such as Figure 1-6 As shown, electronic component 2 includes: mounting frame 21, main board 22, backlight panel 23 and circuit board 24; the mounting frame 21 has a display port 211 and a button 212; the main board 22 is disposed on the mounting frame 21; the backlight panel 23 is attached above the main board 22 and located below the display port 211; the circuit board 24 is connected to the main board 22 through a conductive strip.

[0031] Specifically, firstly, the backlight panel 23 is pasted on top of the main board 22. This direct placement of the backlight panel 23 saves costs and improves assembly efficiency. Next, the circuit board 24 is connected to the main board 22 via conductive strips. Then, the circuit board 24, the main board 22, and the backlight panel 23 are installed into the mounting frame 21, with the backlight panel 23 positioned directly below the display port 211 to ensure good display quality. This allows for the pre-assembly of some electronic components of the electronic scale, reducing the tedious manual installation steps in the assembly line process, effectively lowering the probability of human error, improving product assembly accuracy and consistency, thereby enhancing product quality and production efficiency while reducing production costs.

[0032] In embodiments of this utility model, such as Figure 1-6 As shown, it also includes: a power compartment 15 and a spring 16. The power compartment 15 is disposed on the base plate 13 and a battery is placed inside the power compartment 15. One end of the spring 16 is connected to the battery electrode through a through hole on the power compartment 15, and the other end of the spring 16 is connected to the circuit board 24.

[0033] Specifically, the spring 16 serves as the power supply connection, which eliminates many connecting wires and soldering steps, simplifying the installation process and improving installation efficiency.

[0034] In embodiments of this utility model, such as Figure 1-6 As shown, the widening component 5 includes: an auxiliary plate 51, a trapezoidal groove 52, and a trapezoidal block 53; multiple auxiliary plates 51 are movably connected to the weighing pan 4; trapezoidal grooves 52 are provided at the edges of the weighing pan 4 and the auxiliary plates 51; the trapezoidal block 53 is fixedly connected to the auxiliary plate 51, and the trapezoidal block 53 is configured to cooperate with the trapezoidal groove 52.

[0035] Specifically, align the trapezoidal block 53 on the auxiliary plate 51 with the trapezoidal groove 52 at the edge of the weighing pan 4, and gently push the auxiliary plate 51 so that it can smoothly connect or separate from the weighing pan 4, thereby flexibly adjusting the area of ​​the weighing pan. Then, a rubber pad is attached to the outer surface of each trapezoidal block 53, so that when it is inserted into the trapezoidal groove 52, the rubber pad is squeezed, thereby increasing the friction between the trapezoidal block 53 and the inner wall of the trapezoidal groove 52, thus preventing the auxiliary plate 51 from falling off.

[0036] In embodiments of this utility model, such as Figure 1-6 As shown, the support component 6 includes: a limiting groove 61 and a baffle 62; multiple limiting grooves 61 are respectively opened on the weighing pan 4 and the auxiliary plate 51, and the groove width of the limiting groove 61 is smaller than the diameter of the limiting strip 63; a limiting strip 63 is provided below the baffle 62, and the limiting strip 63 is configured to cooperate with the limiting groove 61, and the cross section of the limiting strip 63 is cylindrical.

[0037] Specifically, when weighing bagged items or other irregularly shaped items, to prevent the items from falling off the weighing pan 4, the limiting strip 63 of the baffle 62 can be inserted into the limiting groove 61, and then four baffles 62 can be installed above the weighing pan 4. This limits the items to be weighed within the rectangular frame enclosed by the four baffles 62. Rubber pads are then pasted on the inner wall of the limiting groove 61, so that when the baffles 62 with the limiting strip 63 are installed, the baffles 62 are more stably installed and less likely to fall off.

[0038] In embodiments of this utility model, such as Figure 1-6 As shown, it also includes: a first card interface 17 and a second card interface 18. The first card interface 17 is disposed on the base plate 13, and one end of the sensor 3 is snapped into the first card interface 17; the second card interface 18 is disposed on the bottom of the weighing pan 4, and the other end of the sensor 3 is snapped into the second card interface 18.

[0039] Specifically, a first card interface 17 is provided on the base plate 13 to stably install the sensor 3 on the base plate 13, and the other end of the sensor 3 is connected to the second card interface 18 at the bottom of the weighing pan 4, so that the weighing pan 4 and the sensor 3 are stably connected. The sensor 3 can accurately sense the weight change on the weighing pan 4, thereby ensuring the accurate transmission of weighing data.

[0040] It should be noted that the specific models and specifications of sensor 3, spring 16, main board 22, backlight board 23, battery compartment 15 and circuit board 24 need to be selected and determined according to the actual specifications of the device, so they will not be described in detail here.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
